Clinton will be forced to describe the creation and operation of the server system that was kept in the basement of her Chappaqua, N.Y. home during her time as secretary of state, as well as the steps her staff took to separate work-related emails from private ones in 2014.

Her responses to the 25 questions posed by Judicial Watch, the conservative-leaning group that brought the suit, will be considered sworn testimony by a federal judge.
